HOW ALPHA WORKS

2 • Nuts are tightened, rotating the end ring.

3 • Draw hooks pull gaskets and grippers outward and against the pipe.

4 • Gaskets compress and seal against the pipe sur face. Gripper teeth are set.

1 • Alpha is positioned over the pipe gap.

Alpha’s grippers and gaskets tighten their hold as the water pressure increases.

A CLOSER LOOK AT SOME KEY ALPHA COMPONENTS

ROTATING END RINGS • During installation, the end rings rotate and slide the draw hooks, gasket and grippers outward and against the pipe sur face.

DRAW HOOK FASTENERS • Stainless steel draw hooks are integrated into the gasket.

INDIVIDUAL GRIPPERS • Individual ductile iron grippers compensate for angular deflection and out-of-round pipe. • Grippers distribute the load evenly around the pipe circumference.
